erm... jar of greed is unlimited, and pot of green is banned (0 allowed) since it's an easy +1. Monster Reborn is back though to combat/punish graveyard mismanagement. But really YGO does have severe pacing problems in terms of good usable cards and rarity compare to Magic. Let's say if you use all common deck in both games, Magic you'll still fight an uphill battle against deck using any card, but you won't face the same degree of decimation like YGO will do to you in the same situation (thus why play on the DS, where rarity totally doesn't matter!)
I could go on for YGO but this is a magic thread I did play Magic before but it was only sorta helping friend understand rules for magic a bit so I only got to play one of the starter decks.
